2. 3A type and 5A TV type

3A type: Contact reliability and break per-
formance best suited for protecting and
switching speakers.
5A TV type: Tough against inrush current
and optimal for turning on and off the pow-
er 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 con-
tact 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 various safety stan-
dards

• UL/CSA, VDE, TÜV, SEMKO, SEV ap-
proved
