Description

General part information

ST1-DC Series

The ST series 1a1b/2a 8A Polarized Power Relay with high switching capability. High contact pressure, low contact bounce and forced separation structure that radically improves resistance to contact welding (1-form-A/1-form-B type equivalent to TV-3). Strong against lamp inductive loads, maximum switching capacity has reached 3040VA (8A 380VAC). High breakdown voltage has been achieved. Between contacts and coil of 3750Vrms, surge breakdown voltage between coil and contact of 6000V and between open contacts of 1200Vrms mean that this relay is suitable even for 250V power circuit control. To improve soldering efficiency, pre-application of solder to the terminals is recommended.
