描述

The 2210-T210-K0M1-H121-3A is a single-pole thermal-magnetic circuit breaker featuring a trip-free mechanism and toggle actuation, compliant with EN 60934/IEC 60934 standards. It incorporates a combi-foot design for both symmetric and asymmetric rail mounting, with one normally open (N/O) auxiliary contact for status signalling. The device is rated for current ratings from 0.1 A to 32 A with a standard M1 characteristic curve (thermal: 1.01–1.4×IN; magnetic: 6–12×IN AC, 7.8–15.6×IN DC), and operates at AC 250 V, 3 AC 433 V (50/60 Hz), or DC 65 V. All screw terminals are recessed for safety, and the unit measures 12.5 mm in width including auxiliary contacts. This circuit breaker is ideal for process control equipment, robotics, machine tool control, communications systems, and instrumentation, offering space and weight savings of at least 50% compared to conventional MCBs.
