CLBA-353-NNFNN-B-A Circuit Breaker Equivalent & Substitute Parts

Part Overview

The CLBA-353-NNFNN-B-A is a thermal circuit breaker manufactured by Carling Technologies, designed for panel mount applications. This single-pole breaker provides overcurrent protection at 35A with dual voltage ratings of 250V AC and 32V DC. The push-to-reset actuator enables manual circuit restoration following a thermal trip event. The part maintains Active product status with full compliance to international safety standards including CE, cUL, TUV, UL1077, and UL1500 certifications. Identification of equivalent substitute parts becomes necessary when managing inventory constraints, lead time requirements, or component availability across supply channels while maintaining identical electrical and mechanical performance specifications.
