Breaking capacity — what it means on your line
At 240 V the unit interrupts fault currents up to 100 kA; at 400 V it holds 30 kA, at 500 V it drops to 5 kA, and at 690 V it's rated for 2 kA. The gL/gG fuse ratings back this up: 80 A at 240 V, 63 A at 400 V, 50 A at 500 V, 40 A at 690 V.
Width is 45 mm, depth 97 mm, height 97 mm. Mounting position is any orientation. Required clearance: 50 mm upwards, 50 mm downwards, 30 mm to the side, 0 mm forwards and backwards — so it packs tight against the back panel. Main circuit connection uses ring cable lugs with M3 screws.
Environmental and duty limits
Operates from -20 to +60 °C with temperature compensation over the same range; storage and transport tolerate -50 to +80 °C. Maximum switching rate under AC-3 duty is 15 operations per hour — fine for occasional motor starts, not for rapid cycling.
