D-SD-Series eries
CIRCUIT BREAKER
Designed for snap-on-back panel rail mounting on either a 35mm x 7.5mm, or a 35mm x 15mm Symmetrical
Din Rail, allowing rapid and simple mounting and removal of the breaker. It features recessed, wire-ready,
touch-proof, shock-resistant terminals, suitable for automatic screwdriver assembly, as well as Dead Front
construction characteristics.
Available with a Visi-Rocker two-color actuator, which can be specified to indicate either the ON or the
TRIPPED/OFF mode, or solid color rocker or handle type actuators. All actuator types fit in the same industry
standard panel cutouts.
Product Highlights: Typical Applications:
0.02 - 50 Amps Industrial Controls
480 VAC or 65 VDC Renewable Energy
1-4 poles (Handle)
1-3 poles (Rocker)
Choice of Time Delays
DIN rail mounting
Precise temperature independent operation
Wiping contacts mechanical linkage with two-step
Finger safe terminals
Common trip linkage between poles
ensures that an overload in one pole will trip all
adjacent poles
