The Phoenix Contact 1020060 is a miniature circuit breaker (MCB) from the TMC 7... and TMC 8... series. The TMC 8... series is UL 489 Listed for branch overload and short-circuit protection, offering an interrupt capacity of 10 kAIC at up to 277/480 V AC and 125 V DC. The TMC 7... series is UL 1077 Recognized for supplemental overload and short-circuit protection, with short-circuit current ratings ranging from 5 kAIC to 7.5 kAIC depending on the supply voltage.
This specific model features a 1A current rating, a 2-pole configuration, and a thermal magnetic breaker type. It is designed for mounting on a 35 mm NS35 rail and has a width of 17.6 mm per pole. The circuit breakers are available with B, C, and D trip curve options and include visual status indication. The trip-free, snap-action mechanism prevents manual override during overload situations.
Typical applications for the TMC 7/8... series include protection of cables, motors, generators, transformers, thyristors, silicon rectifiers, computers and peripheral equipment, industrial process control systems, telecommunications equipment, and power supplies. Accessories such as auxiliary contacts, alarm contacts, shunt trips, and busbars are also available.
