2210-T2 Thermal-Magnetic Circuit Breakers

E-T-A Circuit Breakers 2210-T2 Thermal-Magnetic Circuit Breakers feature a trip-free mechanism and toggle actuation in a compact 12.5mm width per pole. These circuit breakers are available in one-, two-, and three-pole configurations and are designed with a combi-foot for versatile installation on both symmetric and asymmetric rails. The multipole versions are internally linked to guarantee that an overload on any single pole causes all poles to trip simultaneously. E-T-A 2210-T2 Thermal-Magnetic Circuit Breakers prioritize safety through recessed screw terminals, while status monitoring is facilitated by optional auxiliary contacts (1x N/O or 1x N/C). The circuit breakers comply with the relevant requirements of the railway standards DIN EN 50155, DIN EN 61373, and EN 45545. These circuit breakers are built for global applications and feature high vibration resistance (DNV GL Class B). Applications include process control equipment, robotics, machine tool control, communications systems, and instrumentation.
