Description
The Phoenix Contact TMC 81C 01A is a 1‑pole, thermal‑magnetic miniature circuit breaker designed for reliable branch‑circuit protection in industrial and commercial control systems. Rated for 277 VAC and 60 VDC operation with a 1 A trip rating, it provides dependable overload and short‑circuit protection with a C‑curve tripping characteristic. The breaker mounts on a standard DIN‑rail (NS 35) and uses robust screw‑clamp terminals supporting conductor sizes from 18–2 AWG. Built with a durable molded housing and tested for harsh environments, it offers a 10 kA interrupt rating, long mechanical life, and compliance with UL 489 and IEC 60947‑2 standards, making it suitable for control panels, machinery circuits, and distributed automation systems.
