Line protection MCCB with TM210 release
Its TM210 thermal-magnetic release provides adjustable overload response up to 630 A and fixed short-circuit protection — a common choice for feeder and distribution panels where coordination studies set the trip curve. Continuous current holds at 63 A from 40 °C through 50 °C, then derates linearly to 58 A at 70 °C. That means the breaker delivers its full nameplate rating across typical panel ambient conditions without a sizing penalty. Breaking capacity reaches 76 kA at 240 V AC, 53 kA at 415 V, and 32 kA at 440 V.
Dimensions are 101.6 mm wide, 130 mm tall, 70 mm deep, fitting standard MCCB panel cutouts and busbar spacing for 4-pole devices.
Electrical ratings and application context
Maximum power dissipation is 17 W — a factor for thermal management in densely packed enclosures. The TM210 release is field-adjustable for the long-time pickup (Ir) via the front dial, but short-time and instantaneous settings are fixed — a consideration when coordination with downstream breakers requires a selective trip band.
