Product Description

The SCHNEIDER Overload Relay: Thermal Protection (MPN LRD3361) is an IEC thermal overload relay with a 55 A – 70 A range, designed for use with TeSys Deca contactors (80 to 95 Amp models). It features 3 poles, a 1NO/1NC auxiliary contact form, phase loss sensitivity, and integrated bimetallic elements, eliminating the need for separate thermal units. The relay has a maximum voltage rating of 1000V AC and uses screw clamp terminals for connection.

Frequently Asked Questions

What is the SCHNEIDER LRD3361 overload relay used for?

The SCHNEIDER LRD3361 is an IEC thermal overload relay used to protect motors from overcurrent and phase loss. It is designed for use with TeSys Deca contactors (80 to 95 Amp models) in industrial motor control applications, providing reliable thermal protection via integrated bimetallic elements.

What are the specifications of the SCHNEIDER LRD3361 overload relay?

The SCHNEIDER LRD3361 has a 55 A – 70 A range, 3 poles, 1NO/1NC auxiliary contacts, phase loss sensitivity, and a maximum voltage rating of 1000V AC. It uses screw clamp terminals and includes integrated bimetallic elements, so no separate thermal units are required. It is compatible with TeSys Deca contactors.

Where to buy the SCHNEIDER LRD3361 overload relay worldwide?

You can source the SCHNEIDER LRD3361 overload relay through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact us for availability and lead time; we supply genuine SCHNEIDER components for industrial motor protection.

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

To select the correct SCHNEIDER overload relay, match the relay's current range (e.g., 55 A – 70 A for LRD3361) to the motor's full-load current. Ensure compatibility with your contactor series (TeSys Deca for this model) and verify phase loss sensitivity is needed. Always consult the motor nameplate and manufacturer guidelines for proper sizing.
