ENTERLEC

ENTERLEC (TE Connectivity) — DIN‑rail Terminal Blocks, Markers and Accessories

What ENTERLEC is and who owns the brand
ENTERLEC is a specialist brand for DIN‑rail terminal blocks, marking systems and accessories. In 2018 TE Connectivity completed the acquisition of the ENTRELEC terminal‑block business; ENTERLEC products are now marketed within TE Connectivity’s industrial terminal block portfolio.

Core product families and technologies

• Screw‑clamp (SNK / ZS series) — feed‑through and function blocks for general power and signal wiring.
• PI‑Spring / Push‑in (ZK series) — spring‑clamp terminals for fast installation and improved vibration resistance, including ground (PE) variants.
• Pluggable and distribution blocks — modular solutions for subsystem separation and serviceability.
• Markers and holders (MC series) — pre‑printed and printable marker cards and holders sized to block pitch.
• Accessories — end stops, end sections (EK/ES/FEM), jumpers, test connectors and protective covers.

Common applications

Typical uses include industrial control panels, machine OEM wiring, building automation, power distribution, PV combiner boxes, rail and transportation wiring, and MRO work where reliable, serviceable wiring and accessible test points are required.

How buyers identify the right model

Confirm these details before ordering: rated current and voltage, conductor cross‑section (mm² or AWG), connection type (screw or push‑in), pitch and footprint, plus accessory compatibility (end sections, markers, jumpers). TE/ENTRELEC internal part numbers (often starting with 1SNK…) are commonly used in catalogs and help confirm exact matches.

How Safsale helps procurement

• Clear listings with model titles and TE/ENTRELEC part numbers for direct matching.
• High‑resolution images and multiple angles to confirm mechanical features and marker grooves.
• Downloadable datasheets and catalog pages for electrical ratings, dimensions and CAD files.
• Reviews and Q&A where other buyers share fitment and application notes.

Sourcing and replacement guidance

When a direct part number isn’t available, specify replacements by matching connection technology, rated current, conductor size, pitch and accessory fit. Always confirm end‑section and jumper compatibility. For critical power or PV work verify short‑circuit and impulse ratings shown on the datasheet.

Quick buyer checklist

• Match TE/ENTRELEC part number when possible.
• Confirm function (feed‑through, PE, test point, pluggable).
• Download datasheet and compare dimensions with the panel cut‑out and DIN‑rail spacing.
• Validate accessories (EK, ES, BAM, MC marker families) for correct fit.

Summary
ENTERLEC delivers a complete DIN‑rail terminal block ecosystem focused on reliable connections and field‑serviceability. As part of TE Connectivity’s industrial offering, the brand is well supported by datasheets, CAD models and accessory catalogs — and Safsale’s listings and documentation tools help procurement teams confidently find, compare and source the right parts.
