FEATURES
1. 2 Form A slim type
24(L) × 12(W) × 25(H) mm
.945(L) × .472(W) × .984(H) inch
2. 3A type and 5A TV type
3A type: Contact reliability and break performance best suited for protecting and
switching speakers.
5A TV type: Tough against inrush current
and optimal for turning on and off the power supply. Rated TV-4 (UL/CSA).
3. High insulation resistance
• Creepage distance and clearances be-
tween contact and coil: Min. 6 mm .236
inch(In compliance with IEC65)
• Surge withstand voltage between contact and coil: 10,000 V or more.
4. High noise immunity realized by the
card separation structure between
contact and coil
5. Conforms to the v arious safety standards
• UL/CSA, VDE, TÜV, SEMKO, SEV approved
