MOUNTING
Metal, isolated from terminals, isolation voltage: 2500V
RMS.
Bolt down, any position, use 3/16 bolt with spring/belleville washer. Mounting torque = 0.2 kg-M. Use thermal
grease on flat side opposite terminals, when mounting on heatsink or chassis or metal plate; this will ensure
maximum heat dissipation. Metal filled epoxies may also be used instead of bolting.
6.35mm Faston, 3-way suitable for snap-on, warp around or soldering, Corrosion resistant. Soldering (at 180
o
C
for 15 sec. with MRB on heatsink) is recommended for load of 15 Amps and above.
