Battery cutoff relay
3 3 4 Normally open relay
Protects the starter battery against discharge.
For disconnection of an additional second bat-
tery from the starter battery when the alternator
is delivering no charge.
Design: seawater-protected. Relay with reversed-
polarity-protective diode and decay diode for
suppressing inductive voltage peaks.
Switching capacity: 12 V 75 A (400 A, 1 s).
Fastening: 2 holes Ø 5.3 mm.
Connection: screw terminals and blade
terminals.
Dimensions: 75 x 35 mm, height 55 mm.
