Product details

It combines a 32 A MCB with B tripping characteristic and a 10 kA rated short-circuit breaking capacity (acc. to EN 60898) with an AC-type residual current device in a single 36 mm wide, 2-module unit. The 1P+N configuration means it switches the live conductor and monitors the neutral for earth leakage, while the neutral is not switched.

The 32 A rating is the continuous current at 30 °C ambient; above that, the device derates linearly — 30.4 A at 40 °C, 28.8 A at 50 °C, and 24.64 A at 70 °C. Mounting position is unrestricted, and the supply can enter from either top or bottom, which simplifies wiring in tight enclosures.

The product designation follows DIN EN 61346-2 and DIN EN 81346-2 letter code F. Maximum power dissipation is 11.4 W.

Frequently asked questions

What is the 5SU1354-0LB32 rated current at 50 °C?
