1. Scope of application
BS-30 series time relay (hereinafter referred to as relay) is used in power system relay protection devices and automation devices as a delay control element to make the controlled equipment or circuit operate according to the predetermined delay.  

2. Main technical data
Rated voltage: DC 220V, 110V, 48V.
Delay range: BS-31/3-10min; BS-32/5-20rain； BS-33/6-30min； BS-34/1.5-5-minute delay consistency: not greater than 5% of the set value.
Power consumption: not exceeding 15W.
Contact capacity: In a DC inductive load circuit with a positive voltage not exceeding 250V, a current not exceeding 5A, and a time constant of 5 ± 0.75ms, the output contact of the product has a breaking capacity of 50W. Under the specified load conditions, the output contact of the product can reliably operate and return 5 x 104 times. The long-term allowable current for the output contact is 5A.
The conductive terminals of the dielectric strength product are connected together and can withstand an AC voltage of 2000V (effective value) 50Hz for 1 minute without insulation breakdown or flashover between exposed non charged metal parts or shells.
