Tender Summary: Supply and Delivery of Contactors

Objectives

The primary objective of this tender is to procure and deliver two specific industrial electrical contactors manufactured by Siemens. The goal is to secure genuine OEM components that precisely match the specified electrical ratings and contact configurations, ensuring immediate operational readiness without requiring modification or substitution.

Scope of Work

The scope is strictly limited to the supply and delivery of the following items:

• One (1) unit of Siemens Contactor, Part Number 3RT1064-6AF36
• One (1) unit of Siemens Contactor, Part Number 3RT1023-1AF04

All equipment must be delivered new, unused, correctly packaged for industrial transit, and accompanied by all mandatory manufacturer documentation. Installation, commissioning, or maintenance services are excluded from this scope.

Technical Requirements

Bidders must supply equipment that exactly matches the following parameters:

• Item 1 (P/N: 3RT1064-6AF36): Coil potential of 110 VAC, rated current of 225 A, contact arrangement of 2 Normally Open (NO) and 2 Normally Closed (NC), quantity: 1 unit.
• Item 2 (P/N: 3RT1023-1AF04): Coil potential of 110 VAC, rated current of 9 A, power rating of 4 kW, contact arrangement of 2 NO and 2 NC, quantity: 1 unit.

Strict adherence to the specified part numbers and manufacturer is mandatory. Generic alternatives or cross-referenced substitutes are not permitted unless formally authorized through a tender clarification process.

Skills and Capability Requirements

The tender does not outline specialized technical or field skills, as the engagement is purely commercial and logistical. However, bidders must demonstrate standard procurement and distribution capabilities, including:

• Verified authorization or direct sourcing channels for genuine Siemens industrial components.
• Established logistics networks capable of timely delivery to the designated site.
• Ability to provide original manufacturer certificates, type-test reports, and warranty validation upon delivery.

Explanation of Technical Terms

To ensure clarity on specialized terminology used in this specification:

• Contactor: An electromechanical switch designed to repeatedly connect and disconnect high-power electrical circuits, commonly used for controlling electric motors.
• Coil Potential (110 VAC): The alternating current voltage required to energize the internal electromagnetic coil, which physically moves the switch contacts.
• Normally Open (NO) / Normally Closed (NC): Refers to the default state of the electrical contacts when the contactor is de-energized. NO contacts close when the coil is activated; NC contacts open when activated.
• Rated Current & Power: The maximum continuous electrical load (measured in Amperes and Kilowatts) that the contactor can safely interrupt and conduct under standard industrial operating conditions.
