• Main power supply branching
• Modular electrical system installations

When it may not be suitable

This distribution block is not intended for use in environments with extreme moisture or corrosive atmospheres unless housed in an appropriate IP-rated enclosure. It is also not suitable for applications exceeding its 250A rated current capacity or for use with cable cross-sections that fall outside the manufacturer's specified clamping range.

Key specifications

• Rated current: 250A
• Mounting type: TH rail
• Application: Power distribution
• Design: Professional terminal block

How to use

To install the ELS Elektrotechnika BR250, securely snap the unit onto a standard TH rail within your electrical enclosure. Ensure that the power supply is disconnected before beginning any wiring work. Insert the incoming and outgoing conductors into the designated terminals and tighten the screws to the recommended torque to ensure a firm, low-resistance connection. Verify that all cables are properly seated and that the insulation is not compromised before restoring power to the system.

What to consider before purchase

• Verify that your electrical system's current load does not exceed 250A.
• Ensure the available space in your cabinet is sufficient for the block dimensions.
• Check that your cable sizes are compatible with the terminal openings.
• Confirm that your mounting rail is a standard TH type.

Usage recommendations

Always adhere to local electrical codes and safety regulations during installation. Regularly inspect the terminal connections for tightness during scheduled maintenance to prevent overheating caused by loose contacts.
