It carries a MicroLogic 2.2 electronic trip unit configured for LSoI protection — thermal overload (L), short-time short-circuit with fixed delay (So), and instantaneous short-circuit (I). This means the breaker provides coordinated protection for distribution feeders in panelboards rated 250 A or 400/630 A, as per the product destination. ## Protection & Signalling So (short-time short-circuit) has a fixed delay, enabling zone selectivity with downstream breakers without instantaneous trip. I (instantaneous short-circuit) clears high faults immediately. There is no earth-leakage protection on this unit. Local signalling includes a flashing green LED for ready-to-operate status, an orange LED pre-alarm at 90 % Ir, and a red LED overload indication at 105 % Ir. This allows an operator to identify a pre-alarm condition before the breaker trips — useful for planned load shedding in continuous-process lines. ## Mounting & Environmental Ratings The breaker is panel-mounted (backplate) and can be installed horizontally or vertically. It occupies 3 modules of 35 mm width each, so the total width is 105 mm. Depth is 86 mm, height 161 mm. IK07 impact resistance covers low-energy impacts (0.5 J) typical of accidental tool contact. Pollution degree 3 per EN/IEC 60664-1 indicates a conductive or dry non-conductive environment; this is standard for industrial switchgear and requires appropriate creepage distances. Operating altitude is 0–2000 m without derating; above that up to 5000 m requires derating due to reduced air density affecting dielectric strength and cooling. The electrical shock protection class is II (double insulation), so no protective earth connection is needed on the breaker body.","metaTitle":"Schneider Electric MGP1603TX PowerPacT 4 Circuit Breaker, 16","metaDescription":"Schneider Electric MGP1603TX PowerPacT 4 circuit breaker, 160 A at 40 °C, 3 poles, MicroLogic 2.2 electronic trip unit with LSoI protection.
