Phoenix Contact Double Level Terminal Block STTB 2.5-PE Series, 2-Level, Spring Cage Termination, 6kV, Cable CSA 3036026

Phoenix Contact 3036026 STTB 2.5-PE is a double level terminal block designed for compact and reliable circuit connection on NS 35/7.5 DIN rails. Its dual-level design allows control of multiple circuits in a minimized footprint of 67.5 mm height, 5.2 mm width, and 47.5 mm depth. The terminal block accepts cable cross sections from 0.08 to 4 mm² and supports wire sizes AWG 28 to AWG 12, delivering versatility across wiring needs.

This terminal block features a spring cage termination type ensuring tool-free, quick, and reliable connections. The polyamide insulation housing protects against mechanical impact and corrosion while providing excellent electrical insulation to prevent shock hazards.

Operating voltage up to 6kV and temperature range from -50°C to 110°C make the 3036026 suitable for heavy industrial applications including railways and marine environments. Its green and yellow colour coding designates it explicitly as a grounding terminal block to facilitate easy system identification and safety compliance.

The product complies with critical international standards such as VDE for harmonised European safety and EMC regulations, along with approvals including cRUus, GL, and PCT. It also carries hazardous area certifications such as EAC Ex, ATEX, and IECEx, supporting use in explosive or volatile atmospheres.

Supports cables from 0.08 to 4 mm² cross-sectional area for versatile wiring. Operating voltage is rated at 6kV, suitable for high voltage applications. Compact dimensions (67.5 x 5.2 x 47.5 mm) save mounting space on DIN rails.

Polyamide housing provides electrical insulation and mechanical durability. Operating temperature range from -50°C to 110°C for harsh environments. Green/yellow colour coding for easy ground terminal identification. Ideal for industrial, railway, and marine electrical installations.

Conforms to VDE, cRUus, GL, PCT standards and hazardous area certifications EAC Ex, ATEX, IECEx.

This double-level terminal block is essential for industrial automation, electrical distribution panels, rail transport electrification, and marine electrical systems where compact, safe, and reliable connections are paramount. It supports flexible installation and ensures compliance with stringent safety and performance standards.
