Essentials of Schneider C60H-DC DC DC Protector

Key points of engineering application:

For purely resistive loads such as heaters, the C-curve can provide good protection.

For capacitive loads (such as switch mode power supplies), the starting surge may reach up to 20 times the rated current, and the C-curve may trip incorrectly. In this case, a D-type or higher multiple protector should be selected (but this series only has the C-curve, please note).

For inductive loads such as DC motors and solenoid valves, the starting current is usually 6-8 times, and the C-curve is generally applicable.

Attachments and Extended Applications

C60H-DC can be equipped with various electrical accessories (see modules 90081-91103), including:

Auxiliary contact (SD): Used for remote indication of the on/off status of the protector.

Alarm contact: Provide a signal when the fault trips.

Split release (MX): Remote control tripping.

Undervoltage release (MN): Automatically trips when the voltage is too low.

When installing accessories, they must be installed on the left side of the circuit breaker, with a total width not exceeding 54mm. If both SD auxiliary contacts and shunt release are used, the SD should be installed on the left side, and the shunt release should be installed on the left side of the SD.
