It carries a 50 A continuous rating at 40 °C ambient, holds that same 50 A through 50 °C, then derates to 49 A at 55 °C and 45 A at 70 °C, so the panel ambient decides the real ampacity. The 4-pole construction handles three-phase plus neutral, common in North American and some European distribution schemes where the neutral needs overcurrent protection.
Breaking capacity — what it interrupts
The interrupting ratings cover the fault-current range you'd expect on a 50 A feeder: 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 11.9 kA at 500 V and 690 V. The 75.6 kA figure at 240 V means it handles high available fault current on a 240/120 V center-tapped service without series-rating coordination. At 415 V, the 52.5 kA rating covers most European industrial supply points. The TM210 thermal-magnetic release uses a fixed thermal element for overload and a magnetic trip for short-circuit — no electronic adjustment, so it's a straightforward replacement for an existing fixed-trip MCCB.
The breaker measures 130 mm tall, 101.6 mm wide, and 70 mm deep — a 4-pole MCCB that occupies roughly four 18 mm pole spaces on a DIN rail. Front IP40 protects against tools and fingers; the rest of the body is open to the panel interior, so the enclosure's overall IP rating governs.
