CACTA-Z04AA
Description
Electronic timer relay adjustable from 0.2 to 300 Sec in three ranges - 2 timed contacts / 2 instantaneous contacts - 3 A.
To substitute the obsolete BC relay
Pluggable on socket with a withdrawal clasp and square guide pins which can act as a key to ensure that the correct relay is used at the correct voltage (see our withdrawal guide in the technical support pages of this site)
Pluggable on the following sockets : EVB1/CA, ERC1/CA, ERDL1/CA.
