Schaltbau – C310 Bidirectional DC NO contactors for up to 500 A

The C310 is a single pole bidirectional DC NO contactor ideal for all applications with energy recovery. It was designed to ensure safe switching regardless of the current direction and to protect reliably in case of short circuit. The contactor is suitable for typical applications such as the DC end of inverters, combiner boxes of photovoltaic installations, battery storage systems and electric vehicles. The first types in the series are designed for permanent currents of 150 A, 300 A and 500 A. The devices have compact dimensions and low weight.

“The need for reliable contactors for DC applications is growing.

At Schaltbau, we have combined our extensive experience with the latest developments to create the C310 series.

Compact and innovative:
The C310 DC contactor.

a newly developed, highly efficient arc chamber!
The switching medium is air. This eliminates any risk of gas loss.

Single pole and bidirectional,
with double break contacts,
high thermal current,
extremely good breaking capacity,
as well as high short-time withstand current.

To certified safety standards.
Ideal for mobile and stationary applications.

Safe for use with inverters and combiner boxes.
Completely bidirectional thanks to the specially developed arc chamber.

This makes the C310 ideal for applications with energy-recovery.

Also for e-mobility:

The compact C310 serves as a reliable main contact in regenerative systems and battery-powered vehicles.

The C310 series is distinguished by its modular design,
enabling highly cost-effective adaptation to your application.

Compact, efficient, powerful.
