Phoenix Contact PTCB Circuit Breakers

Phoenix Contact PTCB Series Electronic Circuit Breakers provide precise tripping characteristics and flexible protection for critical loads in industrial automation, telecommunications, and control cabinets. These compact breakers are designed for space-constrained environments and are available in fixed current ratings (2A, 3A, 4A, and 6A) or adjustable versions ranging from 1A to 8A. The 48V DC models come with either a fixed 2A nominal current or an adjustable range from 1A to 6A, supporting higher power applications with faster communication rates. The PTCB series includes options with a Normally Open (NO) dry contact output for trip indication and Status Inverted-Reset (SI-R) functionality for digital status output and remote reset. PTCB circuit breakers are UL 508 listed, UL 2367 recognized, and offer NEC Class 2 rated options.
