A Plug-in Horsepower Resistor
®
and armature fuse
must
be ordered and
installed in BC138, BC139, BC140, BC140-FBR, BC141 and BC142.
These should be selected based on the motor’s
rated current
. The price of
the Hp resistor and fuse is included in the BC138, BC139, BC140,
BC140-FBR, BC141 and BC142 list price.
See selection below for catalog number.
Spare resistor kits are available for $11.00 list,

BC141 / BC142
1/100 thru 1.5 Hp
115 VAC Single Phase 50/60 Hz.
1/50 thru 5 Hp
230 VAC Single Phase 50/60 Hz.
Applications:
General purpose industrial use with permanent magnet or
shunt wound DC motors.
Features:
Chassis-mount SCR controls have a free-wheeling diode and
feature adjustable accel, decel, current limit, ±R comp, min and max speed
pots to match applications. The anti-demag feature protects PM motors and
helps protect the SCR power bride against direct shorts. The controls have
US and Canadian U² component recognition.
