Breaking capacity is 52.5 kA at 240 V AC, 32 kA at 415 V AC, tapering to 7.5 kA at 690 V AC. This SCCR range covers most low-voltage commercial and industrial panel feeds up to 690 V line-to-line.
These are the values for the breaker in free air; panel builders should apply additional derating for enclosure fill factor and adjacent heat sources. The case dimensions are 130 mm high, 76.2 mm wide, and 70 mm deep — a standard 3-pole MCCB footprint that fits most DIN-rail or panel-mount assemblies without requiring a larger enclosure. For a panel with multiple breakers ganged together, sum the losses and check the enclosure's thermal dissipation capacity, especially if the panel is sealed or in a high-ambient room.
The TM210 release provides a fixed thermal curve and magnetic trip threshold. At 415 V with 32 kA SCCR, the breaker's instantaneous trip must clear before the downstream device reaches its withstand. The undervoltage release adds a control input for remote tripping or undervoltage lockout, which is common in safety circuits and motor control centers.
