Overload Relays

Overload Relay Solutions for Motor Protection and Industrial Panels

Overload relays are critical for safeguarding motors and control circuits from damage caused by excessive current draw. Whether you're setting up a direct-on-line starter or building automation panels, a correctly rated motor overload relay prevents costly breakdowns by tripping the circuit before thermal limits are exceeded.

At Bank of Lamps, we supply a full range of overload relays — thermal, electronic, and hybrid types — for both single-phase and 3-phase motors. We work only B2B, shipping directly from our 5,100 m² logistics hub.

Types of Overload Relays Available for B2B Integration

Depending on project demands, motor rating, and response speed, we offer:

• Bimetallic overload relays – classic thermal models with adjustable current range
   
• Electronic overload relays – precise digital protection with remote reset
   
• Contactor-mounted overload relays – direct fit to motor starters from ABB, Schneider, Eaton, etc.
   
• Single-phase overload relay units – for compressors, fans, and small pumps
   
• Overload relay 3 phase setups – fully adjustable for industrial motors and HVAC systems
   

All products are available with normally closed trip contacts, test/reset functions, and trip class options (10A, 10, 20, 30).

Matching Overload Relays to Contactors and Starters

We support direct fitment with major OEM contactor lines:

• Schneider Electric – LRD, TeSys D, and GV2-ME
• ABB – TA series, MS132 with add-on overload modules
• Eaton – ZB12, PKZM0 with manual/electronic trip
• Siemens – SIRIUS 3RU and 3RB relays

If you're unsure about compatibility, send us your motor specs or panel layout — we’ll match and quote accordingly.

Key Features for Industrial and HVAC Use

Our overload relays cover a broad range of motor applications:

• Adjustable current settings (typically 0.1 A – 100 A+)
   
• Trip class selections (Class 10, 20, 30) for motor startup profiles
   
• Manual or auto reset options
   
• Auxiliary contacts for signaling or remote interlock
   
• Temperature compensation for ambient variation
   
• IP-rated housings for dusty or damp environments
   

We stock models that meet IEC 60947-4-1, UL 508, and VDE safety standards.

For Control Panels, Starters, and MCCs

Our motor overload relays are used in:

• Industrial motor control centers (MCCs)
   
• HVAC plant panels (compressors, fans, blowers)
   
• Water treatment systems (pump stations, dosing systems)
   
• Conveyor drives and machining centers
   
• Commercial refrigeration systems

They integrate easily with both standalone enclosures and modular DIN rail assemblies.
