Accessories and ordering data Surge suppressor (Varistor) for 3TF46-56 1. Mechanical interlocking kit Mechanical interlock is required when the supply from two different sources is available. Also the same is required for the application involving reversing of motor. Here two contactors are mechanically interlocked with the help of mechanical interlock kit. This ensures closing of only one contactor at a time. Thus prevents a short circuit upon load changeover from one contactor to another.

Contactors for Hoisting Duty AC slipring motors are most commonly used for the hoisting applications. AC2 duty pertains to starting and switching off the slipring motors. In case of hoisting duty breaking current is the starting current and frequency of switching is high. The table shows the making and breaking capacity at normal and at hoisting application where Ie indicates the rated full load current. Making Breaking During Normal operation at full load 2.
Technical Information A. Recommended selection of contactors for hoisting duty In hoisting operation, slipring motors are generally used. For this typical hoisting duty, we recommend the contactors listed in the following table. Contactor Type Stator Protection Maximum load current with hoisting motor. For intermittent duty S3 Rotor Protection Maximum load current with hoisting motor(Delta circuit).

Bimetal Overload Relays 3UA and 3UC The 3UA / 3UC thermal overload relays are suitable for customers from all industries, who want guaranteed optimum inverse time delayed protection of their electrical loads. The relays meet the requirements of IS/IEC 60947-4-1. Application 1 3UA overload relay: 3UA5/6 are 3 pole adjustable bi-metal overload relays mainly suitable for normal starting applications. They provide accurate and reliable protection to motors against overload as per CLASS 10A.
Recovery time After tripping due to overload, the thermal overload relays require some time until the bimetal strips have cooled down. The device can only be reset after the bimetal strips have cooled down. This time (recovery time) depends on the tripping characteristics and strength of the tripping current. The recovery time allows the load to cool down after tripping due to overload. Benefits and features High performance • In-built single phasing protection for -25 to 55° C.

Characteristic Curves Tripping characteristics The current/time curves show the relationship between the tripping time from cold state and multiples of the set current Ie. When the relay is at operating temperature and carrying 100 % Ie, the tripping times are reduced to approximately 25 %. Tripping curve is applicable to 3-pole loads and 2-pole loads. For singlepole loads, the tripping curves lie between curves of 3-pole loads and 2-pole loads.

Motor Protection Circuit Breakers 3VU13 and 3VU16 3VU13/3VU16 is suitable for use in fuseless motor feeders upto 11KW/22KW (25A/63A) respectively. 3VU motor protection circuit breakers are used for protection of motor against overload, single phasing and short-circuit faults. Applications • Motor Protection Circuit breakers type 3VU13 & 3VU16 offer overload, short circuit and phase loss protection for 3 phase motors upto 11kW and 22 kW respectively.
Current Limiting is achieved in 3VU as follows In case of a short circuit, the contacts are opened electrodynamically by the short circuit current. The instantaneous overcurrent release, through the switching mechanism, trips all the three poles of the breaker. A large arc voltage is quickly built up in the arc chamber limiting the short circuit current. Thus ensures faster fault clearing.

Starters Overview Siemens caters with following types of starters to agricultural and industrial sector.
Application Benefits and features The main purpose of motor starters is to start the electrical motor by switching ON the contactor inside the starter. The relay inside the starter additionally protects the motor in case of overload and single phasing condition. The starter is nothing but a pre-wired assembly of contactor(s), relay and ON-OFF push buttons. Direct on line and star delta are two methods of starting the electric motors which is achieved by our DOL and star delta starter respectively.

Useful technical information Method of starting A. DOL starting method: Bimetal Overload Relay: The RAJA direct-on-line starter is fitted with 3UW50 relay. These relays are computer calibrated and therefore, offer accurate protection. The main benefit of this bimetal relay is the built-in single phasing protection in addition to the overload protection. This relay is automatic reset type and can not be reset by hand. Push buttons Push buttons are used for switching ‘ON’ and ‘OFF’ the starter.
In this starter, the changeover from ‘star’ to ‘delta’ is done manually through a control switch. A4. DOL starter with lockable off: Construction: It consists of a star-delta switch (3LAO), contactor (3TW02), an overload relay (3UW50), “Reset” push button and a safety ‘ON’ push button. Operation: This starter is exactly same as RAJA DOL starter with sheet steel housing but the relay needs to be reset manually by pressing OFF PB.
B3. Fully automatic Star-Delta Starter (3TE02) In this starter, the changeover from ‘star’ to ‘delta’ is done automatically after a preset time by using a timer. C. Industrial Starter: C1. DOL (3TW04): This starter is similar to RAJA DOL starter with sheet steel housing (3TW42901A). In order to offer flexibility of selecting exact 3UA relay range by the customer, this starter has only provision for mounting the bi-relay but the birelay is not provided in the starter.
