The Atman BTR 250 VA 230/230V is a single-phase closed-type isolation transformer operating at 230/230V. Its enclosed construction and Class I preparation make it suitable for professional electrical installations requiring galvanic isolation in a compact, self-contained housing.

With insulation classes B, F, and H available and an IP 00 degree of protection, the BTR 250 fits switchgear panels and control cabinets where enclosed transformer designs are preferred.

Key Features

• Single-phase closed-type construction
• 230/230V primary-to-secondary voltage ratio
• Isolation voltage of 3750V AC (for 450 V surge voltage)
• Supports insulation classes B, F, and H
• Class I protection preparation
• Degree of protection: IP 00
• Rated for continuous operation

Product Benefits

• Closed-type enclosure keeps internal windings protected from incidental contact and debris
• Galvanic isolation separates primary and secondary circuits, reducing risk of electric shock and interference
• High isolation voltage (3750V AC) provides a strong safety margin for low-voltage installations
• Multiple insulation classes (B, F, H) allow selection for the required thermal rating
• Compact 120 x 120 x 90 mm footprint makes it easy to fit into tight panel spaces
