Resettable 63A single-pole DC circuit protection
Add a 63A DIN-rail breaker where the complete DC circuit calls for it.
The Renogy Suntree 63A 1P Miniature Circuit Breaker is a resettable single-pole protection device for a correctly designed DC circuit. Its thermal and magnetic trip functions respond to sustained overload and high fault current.

Why this Renogy product
Reusable isolation and overcurrent protection for a matched circuit
Thermal tripThe breaker responds to sustained overload conditions according to its time-current behavior.
Magnetic tripThe magnetic mechanism responds rapidly to high fault current within the device's specified capability.
Manual resetThe handle provides visible circuit control after the fault has been identified and corrected.
System fit
Verify DC voltage, polarity, interrupt rating and enclosure before purchase.
Install only within the exact breaker ratings and applicable rules. Use a compatible DIN enclosure, conductor size and torque, and never substitute the breaker for required source-side protection or disconnects elsewhere in the system.
Single poleThe breaker opens one conductor. Confirm the system grounding and isolation method determines which conductors must be switched.
Fault currentThe available short-circuit current must not exceed the breaker's documented interrupt capability.

Common questions
Buyer FAQ
Can I use it on any 63A controller?
No. Size the breaker for the complete conductor and equipment requirements, including allowed continuous loading.
Is it bidirectional?
Renogy describes the current Suntree 1P breaker family as suitable for reversible current flow; still follow the line/load and polarity markings on the exact device.
Does it include an enclosure?
No. The listing is for the breaker only.
Can I use it beyond its printed DC voltage?
No. Stay within every voltage, current and interrupt rating printed on the exact breaker and documented by the manufacturer.
