Single-phase transformer STM 630VA 400/230V IP00 isolation or safety transformer with single-chamber housing 16253-9998

Single-phase transformer – reliable power supply and safety

This 630 VA, 400/230V single-phase transformer is a robust solution for industrial and electrical applications. Its separation construction provides galvanic isolation, which increases safety and protects connected devices. It is suitable for both new installations and modernization of existing ones.

Construction and application

The STM transformer with a single housing is designed for installation in devices and installations. Thanks to its compact dimensions (150 mm x 120 mm x 155 mm), it is easy to mount even in limited spaces. Insulation class B (130°C) and protection degree IP00 guarantee reliable operation in standard environmental conditions, with a maximum ambient temperature of up to 40°C. This is a separation transformer, which means it isolates the primary and secondary circuits, minimizing the risk of electric shock and electromagnetic interference.

Key advantages

• Galvanic isolation: Ensures user safety and protects sensitive devices from overvoltages and interference.
• Versatility: Suitable for general use in industrial and electrical installations.
• Compact dimensions: Facilitate installation even in tight spaces.
