1D1UL

The 1D1UL is a single-pole thermal magnetic circuit breaker manufactured by Altech Corporation. Designed for industrial and commercial electrical panel applications, this device provides overcurrent protection with a continuous current rating of 1A and a voltage rating of 277V AC. The unit utilizes a thermal-magnetic tripping mechanism to handle both overload and short-circuit conditions efficiently.

Mechanical installation is simplified through its DIN rail mounting configuration, which allows for rapid assembly and secure retention within standard control enclosures. A manual lever actuator enables straightforward visual status indication and manual reset functionality after a trip event. The breaker does not include integrated illumination features.

Certification coverage includes CE marking, cULus listing, and UL489 compliance, ensuring suitability for North American and international market requirements. The component operates under Moisture Sensitivity Level 1 and maintains RoHS3 compliance for restricted hazardous substances. Engineers integrating this breaker into distribution boards or machinery control circuits benefit from its compact form factor and standardized mounting interface.
