NVENT HOFFMAN STB203008 Terminal box, 200x300x80

Why Choose the nVent HOFFMAN STB203008 Mild Steel Terminal Box?

The nVent HOFFMAN STB203008 is a compact and robust mild steel terminal box designed to protect electrical terminals, cable connections and small control components in demanding indoor industrial environments. Part of the nVent HOFFMAN STB terminal box series, it combines durable seam-welded construction with a screw-fixed cover and a high level of ingress protection.

Manufactured from 1.2 mm mild steel, the STB203008 features a RAL 7035 light grey structured powder-coated finish for durable industrial use. Its IP66 protection rating provides complete protection against dust and protection against powerful water jets, while IK08 impact resistance provides additional protection against mechanical impacts.

Measuring 200 mm high × 300 mm wide × 80 mm deep, the STB203008 is particularly useful where installation space is restricted. Four wall-fixing holes and internal M6 studs provide practical installation options, while the one-piece polyurethane gasket helps maintain the enclosure's environmental protection.

Reliable Mild Steel Protection for Electrical Terminations

Industrial terminal boxes provide a secure location for terminal blocks, cable junctions and electrical connections while helping isolate installed components from dust, moisture and other environmental contaminants. The IP66-rated nVent HOFFMAN STB203008 is designed for demanding indoor environments where reliable protection can help reduce the risk of component failure and unnecessary equipment downtime.

The combination of 1.2 mm mild steel construction, seam-welded body and polyurethane gasket creates a durable housing for electrical terminations. Its shallow 80 mm depth is particularly advantageous where mounting space is limited, while internal studs allow compatible mounting plates or DIN rail arrangements to be added when required.

Typical Applications

• Electrical terminal block installations.
• Industrial cable junctions and connections.
• Machine control and automation systems.
• Process control and instrumentation equipment.
• Manufacturing and production machinery.
• Electrical distribution and auxiliary circuits.
• Indoor industrial installations requiring IP66 protection.
