Where the SB04WP Fits — Compact Weatherproof Sub-Board for Outdoor Applications

The SB04WP answers a specific installation requirement — a compact, IP55 rated enclosure for housing a small number of circuit protection devices in an outdoor, exposed, or wet area location where a standard indoor switchboard is not rated for the environment. Four DIN rail module positions accommodate the most common compact sub-board configurations: a main switch plus two or three circuit breakers or RCBOs, or a combination of MCB and RCBO devices to suit the circuits being protected. The transparent polycarbonate lid allows the status of installed devices to be checked without opening the enclosure.

IP55 protection means the SB04WP is dust protected and resistant to water jets from any direction — making it suitable for outdoor walls, undercover areas, construction sites, caravan parks, carport installations, and any other location where weather exposure is a genuine risk. The fire and UV resistant ABS body handles long-term outdoor exposure without degrading or becoming brittle. The UV resistant transparent lid maintains clarity over time, keeping the interior visible for inspection without opening.

The SB04WP is the compact 4 way option in the Transco weatherproof switchboard range. The same enclosure is available in 6 way (SB06WP, L163 x W215 x H100mm) and 12 way (SB12WP, L272 x W215 x H100mm) for installations requiring more module positions. All three variants share the same IP55 rating, ABS body construction, and surface mount format. Circuit protection devices — MCBs, RCBOs, and main switches — are sold separately and must be specified to suit the circuits being protected.

Q: What circuit protection devices are compatible with the Transco SB04WP?
A: The SB04WP accommodates standard DIN rail mounted circuit protection devices including MCBs (miniature circuit breakers), RCBOs (residual current circuit breakers with overcurrent protection), main switches, and other standard DIN rail devices up to 4 module widths. Devices are sold separately and must be specified to suit the circuits being protected.

Q: What does the IP55 rating mean for the Transco SB04WP switchboard?
A: IP55 means the SB04WP is dust protected (first digit 5 — no harmful dust ingress) and protected against water jets from any direction (second digit 5). This makes it suitable for outdoor, construction site, and wet area installations where the enclosure will be exposed to rain, dust, and weather but not high-pressure hosing.

Q: What is the difference between the SB04WP, SB06WP, and SB12WP?
A: The three variants differ only in DIN rail module capacity and enclosure length. The SB04WP accommodates 4 modules (L126mm), the SB06WP accommodates 6 modules (L163mm), and the SB12WP accommodates 12 modules (L272mm). All share the same W215 x H100mm cross-section, IP55 rating, and ABS/polycarbonate construction.
