2. 3A type and 5A TV type
3A type: Contact reliability and break per-
formance best suited for protecting and
switching speakers.
4. High noise immunity realized by the
card separation structure between
contact and coil
5A TV type: Tough against inrush current
and optimal for turning on and off the pow-
er supply. Rated TV-4 (UL/CSA).
5. Conforms to the various safety stan-
dards
• UL/CSA, VDE, TÜV, SEMKO, SEV ap-
proved
