Features
The DC contactor is a special product with a rated current of 400A. Due to the small volume of the product, the power contact will produce a lot of heat when carrying the current of 400A, so it is necessary to install a 200mm2 conductor, and the DC contactor needs to be actively cooled. Generally used in special occasions with limited installation space.2
Epoxy packaging, the contacts are protected by nitrogen, preventing oxidation, strong cooling arc capacity.
High-voltage, high-current control capable.
Compact & low operating sound.
Safety and high contact reliability.
Can be installed in any direction.
Not freezing and condensing at low temperature.
Applications
Golf ball master control system
Forklift master control system
High-altitude work car master control system
Agricultural machinery and garden machinery master control system

Q1: Are you trading company or manufacturer ?
We are a manufacturer.
Q2:What can you do if the product is broken?
Our products come with a one-year warranty from the date of acceptance. If any part breaks within this period and cannot be repaired, we will replace it with a new one. Please note that you will need to cover the shipping costs. After the warranty period, we can negotiate solutions and provide lifetime technical support for our equipment.
Q3:Why should we choose your company?
1. Our company is certified with CE, TUV, UL, RoHS, and IATF16949:2016, among others.
2. We offer advanced technical support and maintain a strict quality management system.
3. We provide efficient and timely service through email, WhatsApp, Facebook, and other channels.
Q4:What is the difference between an epoxy contactor and a ceramic contactor?
1. The sealed materials and processes differ: epoxy contactors use epoxy resin and require a baking process, while ceramic contactors use technical ceramics and require laser brazing.
2. The internal filling gases are different: epoxy contactors are filled with nitrogen, whereas ceramic contactors are filled with hydrogen.
3. The return signal function in ceramic contactors is less stable and reliable compared to epoxy contactors.
