Description


This premium replacement contact kit is specially engineered for ABB EH/EK series AC contactors, covering the full range of models from medium to ultra-high-power industrial contactors. Crafted from high-purity silver alloy material, the movable and stationary main contacts deliver exceptional electrical conductivity, ultra-low contact resistance, and outstanding arc & welding resistance, significantly extending the service life of your contactors and reducing maintenance downtime and costs.

Two standard configurations are available to match different EH series models:

  • For EH50-EH300 models: 1 set = 3 movable + 6 stationary contacts (3 groups, EK series: 4 movable + 6 stationary)
  • For EH370-EH1250 models: 1 set = 6 movable + 6 stationary contacts (3 groups, EK series: 8 movable + 8 stationary)

Designed as a direct, drop-in replacement for original ABB components, this contact set ensures a perfect fit and reliable performance for industrial motor control, low-voltage terminal distribution, power distribution cabinets, and heavy-duty automation systems.

Key Features

FAQs for ABB EH/EK Contactor Replacement Contact Kit

Q1: What models does this contact kit fit?

A: Compatible with ABB EH series: EH50, EH75, EH80, EH100, EH145, EH160, EH175, EH210, EH250, EH260, EH300, EH370, EH550, EH700, EH800, EH1000, EH1250, as well as EK series AC contactors.

Q2: What material are the contacts made of?

A: Silver alloy contact points, Grade A with 85% silver content. It features great arc resistance, high conductivity and long service life.

Q3: What is the configuration of each set?

A:

  • EH50 ~ EH300: 3 movable contacts + 6 stationary contacts (3 groups per set; EK version:4M6S)
  • EH370 ~ EH1250:6 movable contacts +6 stationary contacts (3 groups per set; EK version:8M8S)

Q4: What is this contact kit used for?

A: It is a spare replacement part for worn or burnt main contacts on ABB EH/EK AC contactors. Replace the old contacts instead of buying a whole new contactor to save cost.

Q5: Is this an original ABB spare part?

A: This is aftermarket replacement contact kit, fully compatible with ABB EH/EK series contactors, not OEM original.

Q6: What are the advantages of 85% silver alloy contacts?

A: High silver content provides stable electrical performance, anti-wear, anti-oxidation and anti-arc capability. It reduces contact burnout under heavy current loads.

Q7: How to choose the correct contact kit?

A: Please confirm your contactor model (EH or EK series and specific model number) before ordering, different models have different contact quantity configurations.

Q8: Does one set contain contacts for 3-phase contactor?

A: Yes, each complete set includes all main moving and stationary contacts required for one 3-phase AC contactor.
