TOMZN TOB7Z-63 32A 2P 1000V DC Solar Circuit Breaker
Protect your solar power system with the
TOMZN TOB7Z-63 32A 2-Pole DC Circuit Breaker.
Designed for photovoltaic and compatible DC applications, this DC MCB
helps protect electrical wiring and equipment against overload and
short-circuit faults.
With a rated current of
32A and a maximum rated voltage
of
1000V DC, it is suitable for correctly designed solar
PV strings and DC distribution systems operating within its electrical
ratings. Its two-pole configuration allows both DC conductors to be
switched together when installed according to the required wiring and
polarity diagram.
Key Features
-
32A rated current:
Suitable for compatible solar PV and DC circuits requiring a 32-ampere breaker.
-
Up to 1000V DC:
Designed for high-voltage DC applications within the product’s specified limits.
-
2-pole configuration:
Provides linked switching of both poles in a compatible DC circuit.
-
Overload protection:
Disconnects the circuit when sustained current exceeds the breaker’s designed operating limit.
-
Short-circuit protection:
Provides automatic disconnection during a qualifying short-circuit fault.
-
Manual isolation:
Can also be used for infrequent manual switching of a correctly designed DC circuit.
-
DIN-rail installation:
Suitable for installation inside compatible solar distribution and protection boxes.
-
Solar PV application:
Designed for photovoltaic and other compatible direct-current electrical systems.
Suitable Applications
- Solar panel PV strings
- Solar DC distribution boxes
- PV combiner boxes
- DC-side inverter protection circuits
- Compatible communication and DC power systems
Why Use a Dedicated DC Breaker?
Direct-current circuits require switching and protection equipment
specifically designed for DC operation. The TOMZN TOB7Z-63 is manufactured
for DC applications and helps provide safer circuit interruption than using
an ordinary AC-only breaker in a solar PV circuit.
Package Includes
- 1 × TOMZN TOB7Z-63 32A 2P 1000V DC Circuit Breaker
Important Installation Notice:
The 32A rating must be selected according to the PV string current, cable
capacity, inverter specifications and system design. DC breakers are
polarity-sensitive, and the stated 1000V DC rating depends on correct
two-pole wiring. Installation should only be performed by a qualified solar
technician or electrician.
