Built for Compliant Three-Phase Boards

One device, two jobs

This RCBO merges overcurrent and earth-leakage protection into a single 3 pole unit. Fewer modules, less wiring, and a cleaner switchboard layout — without compromising on protective performance.

Why Type A matters

Type A detects pulsating DC leakage alongside standard AC. That makes it the right choice for boards feeding electronic equipment, drives and switch-mode supplies, where older Type AC devices can fall short.

Curve and capacity

The C-Curve tolerates normal inrush from general power and lighting while tripping quickly on real faults. The 10kA breaking capacity gives the headroom needed for commercial and industrial fault levels.

Q: What does the LSTO10C/003-A protect against?
A: It provides three forms of protection in one device — overload, short circuit, and earth leakage. The 10kA rating handles short-circuit faults, while the 30mA sensitivity guards against electric shock.

Q: Can the LSTO10C/003-A be mounted on a DIN rail?
A: Yes. It mounts on a standard 35mm DIN rail or directly to the Eureka ELS6 chassis, giving flexibility for different switchboard setups.

Q: Is the LSTO10C/003-A suitable for three-phase circuits?
A: Yes. As a 3 pole device it is designed for three-phase circuit protection, switching all three phases together on a fault.
