NEMA 3R Metal Enclosure for 3 Poles MCCB 315A - 630A | Gauge # 16 (Breaker not included)
₱7,800.00
Heavy-duty NEMA 3R outdoor rain-tight metal enclosures made from Gauge #16 (Ga#16) galvanized or cold-rolled sheet steel are standard configurations in the Philippines designed to handle the larger physical frame sizes and heat dissipation requirements of 3-Pole (3P) Molded Case Circuit Breakers (MCCBs) rated from 315A up to 630A.
Because a 315A to 630A MCCB uses a substantially larger frame size (typically a 400AF or 630AF industrial frame) than lower-amperage breakers, these enclosures feature an expanded footprint to allow for strict electrical clearances, bending radius space for thick cables (e.g., 250mm² to 500mm² wires), and structural rigidity.
Key Technical Specifications
- Protection Rating: NEMA 3R (Outdoor weatherproof, rain-tight, and ice/dust resistant).
- Material Thickness: Gauge #16 (Ga#16) steel, which provides the necessary structural rigidity to hold heavy industrial breakers and withstand field impacts.
- Exterior Finish: Industrial gray or beige powder-coated, oven-baked wrinkled finish for superior chemical and corrosion resistance.
- Interior Space: Built with an extended depth (typically 7 to 8 inches) and increased height to manage large industrial terminal lugs and line/load wiring alignment.
- Security & Convenience: Equipped with a drip-shield top, padlockable front latch to restrict unauthorized access, and heavy-duty grounding terminals.
