SB04 Transco 4 Way Pole Module Surface Mount Switchboard Load Centre Din Rail MCB RCBO IP40

Description

4 Way Lockable Switchboard. DIN Rail. Copper Bus Bar. Surface Mount.

The Transco SB04 is a 4 way surface mount lockable switchboard with double row DIN rail and integrated copper bus bar — rated up to 100A at 240/415V AC and IP40 rated for indoor and sheltered installations. It is a step up from the compact ENC enclosure range, providing a complete switchboard solution with transparent lockable lid, integrated copper bus bar for direct device connection, and the capacity for a main switch plus up to three circuit breakers or RCBOs in a single lockable enclosure. Sold as enclosure only — circuit protection devices sold separately.

Where the SB04 Fits — A Complete Lockable Sub-Board for Indoor Installations

The SB04 is the entry-level option in the Transco surface mount switchboard range — providing four DIN rail module positions with a complete lockable enclosure, integrated copper bus bar, and IP40 protection in a compact L112mm footprint. The integrated copper bus bar is the key advantage over the basic ENC enclosure range — it allows circuit protection devices to be directly connected to a common supply bus inside the enclosure rather than requiring separate bus connections. The lockable transparent lid provides both security against unauthorised access and visual inspection of device states without opening the enclosure.

At 100A and 240/415V AC, the SB04 is rated for both single and three phase sub-board applications — single phase at 100A and three phase at 63A. The IP40 rating provides protection against solid objects greater than 1mm, making it suitable for indoor electrical rooms, meter boxes, and switchboard rooms where dust protection is needed but weatherproofing is not required. For outdoor or exposed installations, the IP55 weatherproof SB range (SB04WP, SB12WP) is the appropriate specification.

The SB04 is the compact 4 way option in the Transco surface mount switchboard range. The same switchboard is available in 6 way (SB06), 8 way (SB08), 10 way (SB10), 12 way (SB12), 18 way (SB18), 24 way (SB24), and 36 way (SB36) for installations requiring more circuit positions. All variants share the same copper bus bar, lockable lid, UV and fire resistant ABS construction, and IEC60439-3 compliance. Sold as enclosure only.

Q: What is the difference between the Transco SB04 switchboard and the ENC04 enclosure?
A: The SB04 is a complete switchboard with an integrated copper bus bar, lockable transparent lid, and IP40 protection — rated up to 100A. The ENC04 is a simpler enclosure without a bus bar, without a lockable lid, and with IP30 protection — rated up to 63A. The SB04 is the right specification for a complete lockable sub-board installation; the ENC04 suits simpler compact device housing applications.

Q: What circuit protection devices are compatible with the Transco SB04?
A: The SB04 accommodates standard DIN rail mounted circuit protection devices including MCBs, RCBOs, RCDs, and main switches up to 4 module widths total. The integrated copper bus bar allows direct device connection inside the enclosure. Devices are sold separately — confirm module width before ordering.

Q: Is the Transco SB04 suitable for outdoor installations?
A: No. The SB04 carries an IP40 rating — suitable for indoor and sheltered installations only. For outdoor or exposed locations, the Transco weatherproof switchboard range (SB04WP — IP55) is the appropriate specification.
