ABB SMU615 SMU615HBABBA1AN21G

1. Product Overview

The SMU615 is a dedicated Merging Unit developed by ABB for substation applications. It acquires current and voltage signals from measurement transformers, integrates these signals into a standard digital output format, and provides data support for various power system protection devices. As a member of the ABB Relion® product portfolio, the SMU615 features a compact, simplified and withdrawable design, serving as a core component of digital substations.

The SMU615 does not integrate protection functions itself. Instead, it provides physical interfaces for primary switchgear equipment, including circuit breakers, disconnectors and earthing switches, and is fully configured to perform its core merging unit functions.

【Delivery Time】

1. Express Shipping (DHL, UPS, FedEx, EMS):3-10 working days is a good rule of thumb. These services prioritize speed and often offer features like next-day or guaranteed dezlivery by a certain date (for an additional fee).

2. Air Mail (China Post, Hong Kong Post):7-35 working days, depending on the destination country. This is a more budget-friendly option, but it takes longer because it has lower priority for shipment.

【Important Notes】

Please follow the product’s instruction manual carefully for installation and debugging to avoid damage to the product.
