RXMS1 type fast tripping relayDetailed product description：

Application of RXMS1 type fast tripping relay
Used as an outlet trip in the secondary circuit of the power system.

2 Characteristics
2.1 Fast action, with action times of 3.5-4ms, 5-5.5ms, and 7.5-8ms.
2.2 The contact action can be tested by moving the armature through the small hole on the relay cover.
2.3 Relays can self protect voltage starting current (up to three current holding windings).

Action principle of RXMS1 fast tripping relay
The RXMSl type fast tripping relay is an electromagnetic relay consisting of an electromagnetic system, a contact system, and a bracket. The suction plate is naturally installed on the fixed shaft pin of the magnetic yoke, with very flexible movement. The reaction force is achieved by the reaction force of the contact spring, which ensures reliable, fast, and low-power relay action. The dual contact principle is adopted for the contacts, which improves the contact reliability of the relay and reduces the contact resistance, thereby enhancing the on/off capability of the contacts. The relay housing adopts the imported Combiflex protruding modular insertion structure.
