Notes
1
All 10250T contact blocks shown are suitable for use on standard 10250T and E34 operators. These contact blocks are not suitable for Class I Division 2
type 10250T or E34 devices.
2
Contact blocks with spade terminals are limited to a maximum of one contact block per operator and minimum spacing between devices is 2.5 in (63.5 mm).
Not suitable for use in 10250T or E34 enclosures. Also available in amber housing. Not available with fingerproof shrouds.
3
Special function contact blocks are not suitable for use with roto-push operators, three-position push-pull operators, or four-position selector switches.
4
ECNO contact blocks are not suitable for use with two-position joysticks or when operators are used with padlock attachments.
5
Special purpose 10250T44 contact blocks are not suitable on selector switches or roto-push operators. Okay to use with three-position push-pull operators only
on low voltage (30V or less) circuits.
