Photovoltaic string protection
Two-pole protection for compatible photovoltaic string circuits.
DC distribution circuits
DIN-rail circuit protection after current rating and wiring arrangement are confirmed.
Information to Confirm for Selection
- Required current rating and quantity for each configuration.
- Application and destination country.
- Maximum circuit voltage, including the relevant PV or battery operating limits.
- Prospective short-circuit current at the installation point, if established.
- Grounding arrangement and required conductor switching/protection.
- Whether charging, discharging or other reverse-current conditions are possible.
- Cable and installation details relevant to the selected configuration.

FAQ
What current ratings are available?
Available current ratings are 6A, 10A, 16A, 20A, 25A, 32A, 40A, 50A and 63A.
Is this an MCB or MCCB?
It is a DC miniature circuit breaker (MCB). The page does not describe an MCCB or motor protection circuit breaker.
What should be confirmed before ordering?
Confirm the RTS-DC63-500 current option, maximum circuit voltage, fault-current requirement, grounding arrangement, current direction, quantity and destination country. Ask for the exact supplied model reference and the approved DC wiring and breaking-capacity information for that configuration.
Does 2P define the permitted DC wiring arrangement?
No. The pole count alone does not define the permitted connection, polarity or supply direction. Request the approved wiring diagram for the exact supplied model and system arrangement before installation.
