Product Description

The SCHNEIDER IEC Overload Relay: Thermal Protection (MPN DPER03) is a three-pole thermal overload relay with integrated bimetallic elements, eliminating the need for separate thermal units. It features 1NO/1NC auxiliary contacts, screw clamp terminals, and a maximum voltage rating of 690V AC. Designed for use with TeSys Easy contactors (9 to 32 Amp models), it includes phase loss sensitivity for enhanced motor protection.

Frequently Asked Questions

What is the SCHNEIDER DPER03 overload relay used for?

The SCHNEIDER DPER03 is a three-pole IEC thermal overload relay used to protect motors from overcurrent and phase loss conditions. It integrates bimetallic elements and is designed for use with TeSys Easy contactors (9 to 32 Amp models) in industrial motor control applications.

What are the specifications of the SCHNEIDER DPER03 overload relay?

The SCHNEIDER DPER03 is a three-pole thermal overload relay with 1NO/1NC auxiliary contacts, screw clamp terminals, and a maximum voltage rating of 690V AC. It includes phase loss sensitivity and integrated bimetallic elements, so no separate thermal units are required. It is compatible with TeSys Easy contactors (9 to 32 Amp models).

Where to buy the SCHNEIDER DPER03 overload relay worldwide?

You can source the SCHNEIDER DPER03 overload relay worldwide through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to your location. Contact us for availability and lead time.

How to select the correct SCHNEIDER overload relay for a motor?

To select the correct SCHNEIDER overload relay, match the relay's current range to the motor's full-load current and ensure compatibility with your contactor series. The DPER03 is designed for TeSys Easy contactors (9 to 32 Amp models) and provides phase loss sensitivity. Always verify voltage rating (690V AC max) and pole count (3 poles) per your application.
