Notes:
1. SA indicates that the relay contacts are in the open state upon factory delivery; SB indicates that the relay contacts are in the closed state upon factory delivery. Unless otherwise specified by the customer, our company will default to shipping the relay with its contacts closed.
2. UC3: The product conforms to clause of GB/T 17215.231 2021: making capacity: 3kA/10ms, withstand capacity: 6kA/10ms.

Notes:
1. When latching relays are installed in equipment, coil should not be pulsed with less than the nominal coil voltage and pulse width should be a minimum of three times the specified operate time of the relay. If these conditions are not followed, it is possible for the relay to be in the magnetically neutral position.
2. Do not apply voltage to the coil for a long period (more than 1 minute).

Remark :
1.Latching relays leave the factory with the contacts in the closed (reset) position. However, shocks during shipping or installation can alter this state. Thus, prior to use (upon power-up), it is necessary to take action to reset the relay.
2.Normally the load terminals are not suitable for reflow solder, wave solder or tin solder, we suggest use spot welding. Load terminals shall be prevented from mounting stress, or freely move .
3.Relays used for metering measuring applications are usually made with dust proof structure, while most relays could be made specially per customer's specific requirements. No longer than 6 months storage time is recommended for this kind of relay, and please pay attention to the storage environment.
