AED 175.00
- Ships to Saudi Arabia and across the GCC from Dubai stock, with SASO and SABER conformity documents prepared in advance (about 7-10 days road freight to KSA).
- Genuine TENGEN TGM3DC-125: 125A, 2-pole, up to 500V DC, 25kA breaking capacity (Icu) to IEC 60947-2.
- Protects solar PV strings and combiner boxes, battery and BESS banks, and DC distribution boards up to 500V DC.
- Purpose-built DC arc-quenching - never protect a DC solar or battery circuit with an AC breaker.
- Every unit checked by our in-house engineer before dispatch; we will confirm 2-pole 500V vs 4-pole 1000V for your system.
- WhatsApp a quote or stock check to +971 55 414 9418 with your quantity and system voltage.

The TENGEN TGM3DC-125 is a 125A, 2-pole moulded case DC circuit breaker (DC MCCB) rated up to 500V DC with a 25kA breaking capacity (Icu) to IEC 60947-2. It is built to protect direct-current circuits in solar PV, battery storage and DC distribution systems, where a standard AC breaker cannot safely interrupt a fault. This page is written for solar installers, panel builders and procurement engineers specifying DC protection for UAE and GCC projects.
Quick Specs
- Rated current is 125A, the top rating of the TGM3DC-125 frame, with lower ratings from 16A to 125A available in the same series.
- Rated operating voltage is up to 500V DC in the 2-pole configuration, with a 1000V rated insulation voltage (Ui).
- Ultimate breaking capacity (Icu) is 25kA at 500V DC, tested to IEC 60947-2 for reliable DC fault interruption.
- Two-pole moulded case construction with a DC arc-quenching design, so it clears DC faults that an AC-rated breaker cannot handle.
- Built for continuous DC service in solar PV, battery and BESS, and DC distribution circuits rated at or below 500V DC.
- Genuine TENGEN stock held in Dubai for fast UAE and GCC dispatch, with help preparing SASO and SABER documents for Saudi Arabia shipments.
Applications and Compatibility
- Solar PV string and combiner-box protection on arrays where the DC bus voltage is at or below 500V.
- Battery energy storage systems (BESS) and battery banks operating within the 500V DC class.
- DC distribution boards and industrial DC control circuits up to 500V DC.
- Telecom and data-centre DC power feeds within the rated voltage.
- For 1000V or 1500V PV strings, use the 4-pole version of the TGM3DC series instead. Ask our engineer to confirm the correct pole and voltage class for your system.
Why Buy From Electrical Junction
- Genuine parts checked by our in-house engineer before every dispatch, not grey-market stock from an anonymous marketplace.
- Held in stock at our Naif, Deira counter in Dubai for same-day collection or fast UAE delivery.
- Export-ready for Saudi Arabia and the GCC: we can help prepare your SASO and SABER conformity documents in advance, with road freight of roughly 7 to 10 days from Dubai.
- Bulk and project quantities quoted the same day, with engineer support to confirm the correct pole and voltage class for your DC system.
Frequently Asked Questions
What is a 125A 2-pole DC MCCB 500V used for?
It protects direct-current circuits against overload and short circuit up to 500V DC, mainly in solar PV strings and combiner boxes, battery and BESS banks, and DC distribution boards.
Is this DC MCCB rated for 1000V or 1500V solar strings?
No. This 2-pole version is rated up to 500V DC only. For 1000V or 1500V PV strings you need the 4-pole version of the TGM3DC series, so send us your system voltage and we will match the correct model.
What is the breaking capacity?
The ultimate breaking capacity (Icu) is 25kA at 500V DC, tested to IEC 60947-2.
Can I use an AC MCCB on a DC solar circuit instead?
No. DC current has no natural zero-crossing, so a purpose-built DC MCCB with a DC arc-quenching chamber is required for safe fault interruption.
Do you supply to Saudi Arabia with SASO and SABER documents?
Yes. We dispatch from Dubai to KSA and the GCC, and we can help prepare your SASO and SABER conformity documents in advance so shipments clear customs without delay.
