Siemens 5TE2515-1

The Siemens 5TE2515-1 is a high-performance 1-pole switch disconnector designed for the 5TE2 series, offering robust manual isolation for single-phase circuits. Engineered in Germany, this 20A device is specifically rated for AC-23A utilization, making it capable of frequent switching of highly inductive motor loads or other demanding electrical tasks. Its compact thermoplastic housing and standard DIN rail compatibility ensure seamless integration into industrial control panels and commercial distribution boards requiring reliable 415V isolation.

Quick Answer

The Siemens 5TE2515-1 is best used as a manual isolation point for single-phase auxiliary circuits, small motors, or control gear in industrial and commercial panels requiring a 20A, 415V rated single-pole disconnector.

✓Heavy-duty AC-23A utilization category for motor load switching.
✓High voltage tolerance of up to 415V in a single-pole configuration.
✓Reliable rotary operation mechanism for positive contact indication.
✓Durable German-engineered thermoplastic housing with IP40 protection.
✓Universal 35mm DIN rail mounting for rapid installation in modern panels.

Choose the Siemens 5TE2515-1 if you require a space-efficient, single-pole isolation solution with industrial-grade switching capacity (AC-23A). It is the ideal component for localized motor disconnection or control circuit isolation where 20A capacity and German manufacturing standards are non-negotiable.

✓ Who Should Buy

  • •Industrial panel builders requiring compact single-phase isolation.
  • •Maintenance contractors servicing legacy Siemens 5TE2 series installations.
  • •OEMs integrating small motor control systems requiring 415V rated switches.

✕ Who Should Avoid

  • •Users requiring 3-phase (3-pole) simultaneous disconnection.
  • •Applications requiring integrated overload or short-circuit trip functionality.
Product Overview
The Siemens 5TE2515-1 stands as a cornerstone of the 5TE2 series, representing a legacy of electrical safety and precision. Since its introduction in 2010, this model has been the go-to choice for engineers seeking a compact yet powerful 1-pole disconnector. Unlike standard toggle switches, its rotary mechanism provides a tactile and secure method of circuit isolation, ensuring that downstream maintenance can be performed with total peace of mind. Technically balanced for 20A applications, the 5TE2515-1 excels in environments where space is at a premium but electrical integrity cannot be compromised. The screw terminal design provides high-torque connectivity, reducing the risk of thermal hotspots. While it lacks internal overcurrent protection, its role as a dedicated switch-disconnector allows it to withstand significant stress during manual operations under load, particularly in systems utilizing 415V single-phase configurations.

Engineering Analysis
The 5TE2515-1 utilizes a high-grade thermoplastic resin housing that maintains structural integrity under fluctuating thermal conditions. The internal contact bridge is optimized for low contact resistance, ensuring the 20A rated current does not lead to excessive voltage drops. As a non-automatic switch, it does not feature a trip unit; instead, it relies on its mechanical endurance and high insulation voltage (415V) to serve as a 'safe-break' point in a multi-tier protection strategy. The absence of short-circuit protection means it must be coordinated with upstream Siemens 5SY or 5SL miniature circuit breakers.
