CLB-043-27J1N-B-A/04 Description

Short technical summary and product information.

This thermal circuit breaker is a single-pole, panel-mount device rated for 4A at 250V. It uses a push-to-reset actuator and has no illumination. The breaker carries CE, cUL, TUV, UL1077, and UL1500 approvals.

 

The thermal breaker provides overcurrent protection in a compact panel-mount form factor. The push-to-reset actuator allows manual reset after a thermal trip. The single-pole configuration is appropriate for protecting individual circuits.

 

Panel mounting simplifies installation in control panels, power distribution equipment, and enclosures. The unilluminated actuator avoids the need for indicator lamp wiring.
