Rated 32 A with a C curve means the magnetic trip threshold is 5 to 10 times the rated current — standard for inductive loads like small motors and lighting banks where inrush is moderate. The 4.5 kA breaking capacity at 230/400 V AC is the maximum fault current it can safely interrupt; if your panel's prospective short-circuit current exceeds that, you need a higher-rated upstream breaker or a current-limiting device. Single-pole (1P) construction switches only the phase conductor. This is typical for single-phase branch circuits or for protecting one leg of a three-phase load where neutral is not switched. The 18 mm width per pole means this 1P unit occupies one module position.
Deployment context
This is a distribution-grade MCB for final subcircuit protection in residential or light commercial panels. The IP20 finger-safe terminals suit enclosed distribution boards — not outdoor or washdown locations. Terminals accept 1 to 35 mm² rigid or 1 to 25 mm² flexible conductors, with a tunnel-type connection. Tightening torque is 3.5 N.m; strip length is 14 mm for AC wiring. Rated operational voltage is 230/400 V AC, 50/60 Hz. The breaker is certified to IEC 60898-1 and the Indonesian standard SNI 04-6507.1.
Environmental and durability
Operating temperature range is -25 to 60 °C; storage range is -40 to 70 °C. Electrical endurance is 10,000 cycles at rated voltage; mechanical endurance is also 10,000 cycles.
