How to get the id from the custom category?

How do i get the ID from the current custom taxonomy (category) the user is browsing?

It uses a custom post type called “products”
The categories are called “pcategories”

With normal categories i would get it like this:

<?php if ( is_category() )  
{  
    $cat= get_category( get_query_var( 'cat' ) );
    $cat_id = $cat->cat_ID;
    $categorytable = myrp_api_comparison_table( $category = $cat_id, $number = null, $visit_text = "Visit Text", $image_set = null, $custom_fields = null, $rating_categories = null, $return = false );
    if(empty($categorytable))
    {} else 
    {           
    echo $categorytable;
    } 
} 
?>

So how would i do this with custom taxonomies?

If i do:

<pre><?php print_r($wp_query->query_vars); ?></pre>

I get:
